...the Tibetan Book of the Dead teaches that it takes forty-nine days for the soul of the recently dead to "reincarnate"... it takes forty-nine days from conception for the first sign of the human pineal to appear. Forty-nine days is also when the fetus differentiates into male or female gender.

A good case for the re-incarnationists!

Also the possible DMT eruption in the mind at birth, then mirrors the very same DMT eruption at death (and then there's all the DMT you smoke in-between)!
